@JustFuckingWatchCowboyBebop DELIVERED!

Last week I stumbled upon this profile description. I posted it, and this pleased the Imgur Gods, and it made FP. Soon after, @JustFuckingWatchCowboyBebop contacted me about his generous offering.
(Note: I watched the show when I was a teenager, and fell in love with it. I've always wanted to show my little sister, and I thought this might be the opportunity.)

"3,2,1 -- Let's Jam!" A few days later a package arrives and I race home to collect my bounty.

"BANG." A stranger from the internet sent me a package. Who could this mysterious stranger be? And what ever does this package contain?
